关于json数组取值问题
var e=[{"id":"6","name":"宫保鸡丁","num":"1","price":"0.01","image":"54eff88f43a7a.jpg"},{"id":"5","name":"宫保","num":"2","price":"0.01","image":"54eff88f43a7a.jpg"},{"id":"9","name":"鸡丁","num":"3","price":"0.01","image":"54eff88f43a7a.jpg"},{"id":"3","name":"宫丁","num":"5","price":"0.01","image":"54eff88f43a7a.jpg"}]
json如上,请问如何通过id把对应的num取出来,本人小白,没学多久,请大神指点
